To all whom '5t-mayy concern:

Be it known that I, FRANCIS E. COLLINS, a citizen of the United States, residing at the county of Monts gomery and State of Pennsylvania, have invented a certain new and useful Improvement in OilFilters,f of Whichthe"v following is a specification. 4 Y

My invention relates to a newand useful improvement yinoi-l ilters, and has for its ob'ject'to Aprovide. an exceedingly simple and eifective device of this character,- whereby the olinaybe readily, quickly and 'thor-- oughly filtered Another object of the invention is to construct the filter that the foreignv matter after being excluded from from the filter by steam.

A further object of the invention is to so arrange the filtering parts as to prevent their displacement when Athe steam is being used to. blow out the foreign matter.

Another object is to provide drains so that the filtered oil may be drawnfrom the filter before the steam is allowed tov enter, and also the oil between the shell and filtering tube drained out.

A Still further object of the invention is to .provide a pressure gage situated upon the suppl-y pipe so'that the-operator may know whenit is necessary to-clean the filter.

With these ends in view, thisinvention consists in the details of'construction and combination of' elements hereinafter set forth and then specifically-designated by the Claims'. A

In order that those skilledin the art towhich this invention a pertains may understand how to make and use the same, I will describe its construction in det-ail, referring by letter to the accompanying drawlng forming a part of this 'zspecific'atiom in which- ,Figure l shows two lters--made in accordance with my improvement, asthey` are connected in pairs, one of said filters. bein shown in section, and Fig. 2, a horizonte sectional view of the filtering tube and its coverings.

In carr ing out my invention as here embodied, represents the filter tank, in which isv placed a filtering tube B, having perforations C, and this tube is provided at each end with a head D, through which passes a perforated pipe E, said pipe being situated in the axial center of the filtering the oil may be blown.

wire gauze is wrapped a suitable fabric G,

v which is preferably muslin.` In placing the fabric upon the ktube it is wound around and around .and drawn very .tight until a considerable ,thickness is ob- ;tained,`and in order that this may be held securely in place, I wrap a wire H about it. lThe strands of this wire are. wound very close for some distance at the top and bottom, while in between the strands are some distance apart, at about one-half inch pitch. When the filteringtubel and,- its coverings are in place in the vfiltering tank, there is ,still considerable space int'o which the oil -may enter.

Leading to.. the filtering tank is a pipe I, -in which is situated a valve J, and leading to this pipe is a 4supply pipe K, through which the oil Vpasses from the pumps. v Where theseA two` pipes join is connected the y gage pipe L, on which is mounted the pressure gage M.v As the oil is punped through the supply pipe Kyit passes through the pipe I into the filter tank and is gradually lforced intothe iltering tube through its coverin s, from which place it'passes' into thel er orated tube E into the outlet pipe N to t system uated therein.

To- 'the outlet pipe vN is connected the steam pipe `R which leads from the steam boiler. v I

The' lower end of the v perforated 'pipe E is connected to the drain pipe. S, having a valve T, andthis drain pipe is connected with the return pipe U, which leads to the receiving tank so that it may be again returned to the pumps. and the pumps are not shown since t ey do not pertain tomy improvement.

represents a blow oli' pipe leading from the bottom ofthe filter tank and from. this branch the pipes W and X, each having a .valve Y and Z situated therein. The pipe `W leads to the receiving tank and if found desirable may be connected with the return pipe U. The pipe X leads to the atmosp ere.

In practice while the oil is being filtered the valvesv J and Q are open, while the valves T and V are closed/this permits the oil to pass through the supply pipe K and pipe I and into the tank and because of the pressure, the` oil will be forced through pipe O, having a valve Q, sit- Y The receivin tank atmosphere throug 'filtered oil within the the fabric G and wire gauze F into the filtering tube, the foreign matter in the oil remaining upon the outer circumference of the fabric. After the voil has entered the filtering tube it will pass into the perforated pipe Ev and through the outlet pipe N into theI system pipes O.

Should the filter become clogged, that is, the fabric become fully coated with the foreign matter, it will be very difficult for the oil to pass into Athe filtering tube B, which will cause the pressure to be raised,

and this will be indicated upon the ressure gage M, notifying the operator t at the filter needs cleaning.

To clean the flter, the valves J and Q are closed and the valve T o ened, allowing the tering tube tol flow throu h the drain S into the return pipe U, and a ter this oil has drained off, the valve T is closed and either valve Y or Z opened, it .being understood that the valves J and Q,

remain closed, the steam is then allowed to Of course I do not wish to be limited tothe exact details of construction here shown,

Aas these may be varied within the limits of the appended claims without departing from the splrit of my inventionl Having thus fully described my invention, what I claim as new and useful is- 1. In an oil filter, the combination with a filtering tank having an inlet and an outlet, of a perforated filter tube having imperheads, wire gauze mounted upon the outer circumference of said tube, a fabric woundabout said wire gauze, and means for holding said fabric in place.

2. 'In an oil filter, the combination with a filtering tank having an inlet and an outlet,

Vof a perforated filter tube having imperforated heads, wire gauze'mounted upon the outer circumference of said tube, a fabric Wound about said wire gauze, a wire wound about the fabric' for holding it upon the tube, and a perforated pipe passing through Lthe ltering tube, its ends projecting beyond both heads.

3. In combination, \a `filtering tank, a valveor blow of cock leading therefrom, asupply pipe leading to' said tank, a pres'- sure gage situated therein, a valve also situated 1n said supply pipe between the pressure gage and tank, a drain pipe leading vfrom the'tank, a valve' situated therein, a return pipe connected with the drain pipe, an outlet pipe, a System pipe having connection with the outlet, a steam pipe also having connection with saidr outlet, a perforated filterin tube mounted within the tank, an imper orated head upon each end of said tube, a wire gauze placed about the filtering tube, a fabric wrapped about the wire gauze for ay number of thicknesses, a wire placed about said fabric for holding the fabric 'against displacement, and a perforated pipe passing through the filtering tube, the ends of which project beyond the heads and have connection with the drain and outlet pipes.

4. In an oil filter the combination of a filtering tank, of a perforated filtering tube having imperforated heads, a pipe perforated throughout that portion between the heads of the filtering tube, the ends of said pipe extending beyond the heads of the iltering tube and supporting said filtering tube within the filtering tank so that none of its part-s are in contact Withsaid filtering tank, wire gauze lying against the outer surface of said filtering tube, a fabric in contact with said wire gauze, and means for holding the fabric in place.

In testimony whereof, I have hereunto affixed my signature in the presence of two subscribing witnesses.
